XX Rear Derailleur
Leveraging the legendary history of SRAM shifting, the XX Rear Derailleur delivers incredible speed and precision. Sealed ceramic pulleys give you the highest levels of durability. The carbon fiber cage has a dedicated length specific to 2×10. Exact Actuation technology eliminates slop and shifting variation. It’s a rear derailleur perfected for ultimate off-road performance.
The revolutionary machined design of the XX Cassette uses the same grueling manufacturing techniques that produced the PowerDome road cassette. With X-Dome, eight of the cogs are CNC-machined together out of a single block of billet steel, creating an incredibly lightweight, precise, and strong cassette. It’s a process that takes nine hours per cassette! The aluminum large cog can be replaced as needed. You have never seen a cassette that looks like this. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.
